Improving Power Plant Performance

RJM International is an award-winning specialist in combustion technology and emissions reduction, serving the global power generation, industrial energy, biomass, and waste-to-energy sectors since 1977.

With over 60 GWe of successfully completed projects and more than 300 customers worldwide, RJM delivers proven, field-tested engineering solutions.

From custom ultra-low NOx burner retrofits to complex coal-to-gas conversions, our comprehensive product and service suite empowers utility-scale power plants and industrial facilities to optimize heat rates, enhance operational flexibility, and seamlessly satisfy local, state, and federal EPA compliance standards.

Tailored Engineering & Combustion Technologies

To navigate evolving regulatory demands and fuel market dynamics, US power generators require proven, highly customizable combustion solutions. RJM delivers end-to-end engineering solutions, tailored to your facility’s precise operating profile.

Our capabilities span major fuel retrofits including full coal-to-gas conversions, as well as bespoke ultra-low NOx burners for process plant and other multi-fuel firing systems.

We utilize advanced Computational Fluid Dynamics (CFD) modeling and comprehensive combustion audits to identify efficiency bottlenecks, lower emissions, and prevent boiler slagging and fouling. Our IMPULSE® online cleaning technology maximizes uptime without sacrificing heat rate.

Discover below how our full spectrum of combustion engineering and emissions reductions services, including our range of high-performance equipment can optimize your plant operations.
